Changes

The story that Test Track told began when guests entered the queue. Once in line, they entered an area that was themed to look like an industrial testing laboratory. In the laboratory, there were two different kinds of tests. First, in thee Quality Zone, guests could see how General Motors used various technologies in their vehicles and how these components were tested. The second part of the queue consisted of the Quality Zone where guests could see how brakes, wheels, airbags, suspensions, seat belts and the windshield were all tested. As guests moved further into the queue they could see various "Snap-On" tools and GM test machine, while television sets showed other tests being performed. After passing through the turnstiles, guests reached the preshow room. Here, guests they would watch a video hosted by Bill McKim. Bill told a technician that he wanted to set up certain tests, as guests watched a short clip showing what each test would entail. Before guests boarded their cars, Bill told the technician that he wanted a "surprise test", which was accompanied by a clip of a car crashing into a barrier. After watching the video guests proceed to the loading area, where they boarded their cars.  

'''Brake Test'''- The next tests test that guests went through was the brake test. First, the cars car's anti-lock braking system was turned off, as the car tried to navigate through a cone course. With the system off, the car knocked over many cones. Next, the anti-lock braking was turned back on and the car was easily able to navigate the course. After completing the second course, guests watched an instant replay of the tests to reinforce how important the anti-lock breaking system is. 

'''Environmental Chambers'''- After going through the brake test, guests enter the cars entered the Environmental Chambers. Here, they guests were exposed to extreme heat (110°F), and extreme cold (10°F), and before they were even sprayed with a corrosion mist by robots.

'''Ride Handling Test'''- The next test that the guests endured , tested the car's handling. In the handling tests, the car climbed up a series of hills, while increasing its speed and making blind turns. At the top of the hill the car almost drove directly into an oncoming semi, before dodging it at the last second.

'''Barrier Test'''- After completing the handling test, guests experienced the test shown in the preshow film: the barrier test. At this time , the car lined up with a barrier and began to accelerate towards it. Just before hitting the barrier however, a series of flashes occurred and the barrier flew out of the way. At this point guests guest's picture were taken, which could later be purchased in the pavilion’s shop.  '''High Speed Lap'''- After the barrier moved away guests found themselves outside and moving at a much faster rate. As the car took a lap along the banked roadway, guests could reach speeds of up to 65 miles per hour. After the lap had ended, a thermal scan was taken of guests before they unload into the gift shop.

 Test Track’s original postshow featured a showroom which held past, present , and future GM cars. A gift shop was also located here, where guests could buy their on-ride photo, as well as Test Track and Epcot merchandise. 

The new version of Test Track begins with guests entering the Chevrolet Design Studio. After passing by two prototype cars, guests see a model car being worked on while a Chevrolet employee explains how cars are designed. Moving past the model car, guests split into two lines where they wait, before entering into a design studio. Within the studio, guests have a period of time (which varies depending on the attraction's wait time) to design their own car , which they will then test on the "sim-track". After designing their vehicle, guests enter a second queue where they wait to board the attraction. Before getting into the ride vehicles, guests scan their RFID chip in order to upload their car into the ride.

The third test that guests go through on Test Track is the responsiveness test. Here, the sim-car accelerates and takes sharp turns around laser trees, before entering a tunnel and narrowly missing crashing into a semi. After seeing their responsiveness scores, guests go through the power test. After momentarily stopping, the sim-car accelerates through a series of flashing purple arches and into a wall , (which has the Test Track logo on it, which ) that flies open. After passing through the wall, guests find themselves on the exterior track where the car continues to accelerate, taking a right turn, a wide left turn, and then finally one more long left turn. Following the power test guests arrive back at the loading area. 

The new Test Track postshow features several new interactive exhibits. One exhibit allows guests to drive a miniature version of the car that they created , around a digital track. Another exhibit allows guests to create a Chevy commercial using featuring their car. In the postshow guests can also see how their car’s scores stacks up against other guests and , as well as take photos with some of Chevy's prototype cars. Finally, the postshow area also allows features a Chevrolet Showroom and a gift shop.
